All current waterproof jackets are treated with what is known as a Durable Water Repellent (DWR). DWRs today can be grouped into two categories: those containing perfluorocarbons (PFCs), and those that cannot repel oil. The first category is problematic because PFCs are toxic to humans, with exposure causing lowered birth weight, pregnancy complications, and immunocompromised children. Canada has recognized this, and PFCs will be completed phased out by 2023. However, today only PFC-containing DWRs exhibit oil repellency. That's why the second category of DWR exists: some apparel manufacturers have traded their clothing's oil-repellent properties for increased environmental and human health. Unfortunately, oil repellency is vital to keep sweat out of the fibres of apparel. Without oil repellency, jackets are easily soiled and then loose their waterproof properties. Arc'teryx, the Vancouver-based sportswear apparel manufacturer, recognizes the inherent difficulty in this problem: their products requite both oil repellency and environmental sustainability, for which today there is no solution on the market.****The purpose of this project is to develop a non-PFC DWR that exhibits oil repellency. Dr. Golovin's research group at UBC has teamed with Arc'teryx for this endeavor, in order to develop the first oil-repellent textile finish that is PFC-free. Golovin's group has recently discovered that nano-silicones can repel oil even though typical silicone materials get completely wet by oils. This project will explore how nano-silicones can repel oils, how these nano-silicones can be applied to textiles, and how this new textile finish can be made durable enough to meet Arc'teryx's performance needs. By the end of this 36-month project it is expected that a PFC-free textile finish, based off of nano-silicone technology, will be ready for mass production and application in all of Arc'teryx's textile mills.******

目前所有的防水夹克都经过所谓的耐用防水剂 (DWR) 处理。如今的 DWR 可分为两类：含有全氟化碳 (PFC) 的 DWR 和不能防油的 DWR。第一类是有问题的，因为全氟化碳对人类有毒，接触后会导致出生体重降低、妊娠并发症和儿童免疫功能低下。加拿大已经认识到这一点，并将于 2023 年完成 PFC 的淘汰。然而，目前只有含 PFC 的 DWR 具有拒油性。这就是第二类 DWR 存在的原因：一些服装制造商用服装的防油性能来换取改善环境和人类健康。不幸的是，防油性对于防止汗水进入服装纤维至关重要。如果没有防油性，夹克很容易弄脏，然后失去防水性能。总部位于温哥华的运动服装制造商 Arc'teryx 认识到这个问题的内在困难：他们的产品需要防油性和环境可持续性，而目前市场上还没有解决方案。****该项目的目的的目标是开发一种具有拒油性的非 PFC DWR。 UBC 的 Golovin 博士的研究小组与 Arc'teryx 合作开展这项工作，以开发第一种不含 PFC 的拒油纺织品整理剂。 Golovin 的研究小组最近发现，即使典型的有机硅材料完全被油润湿，纳米有机硅也可以排斥油。该项目将探索纳米有机硅如何防油、如何将这些纳米有机硅应用于纺织品，以及如何使这种新的纺织品整理剂足够耐用，以满足 Arc'teryx 的性能需求。在这个为期 36 个月的项目结束时，预计基于纳米有机硅技术的无 PFC 纺织整理剂将准备好在 Arc'teryx 的所有纺织厂进行大规模生产和应用。***** *
